Add tomatoes, salt, black pepper, oregano, basil, and puree.
1 Medium Tomato
Bring to a boil, then simmer covered for two hours. Stir occasionally, crushing the tomatoes with a potato masher.
Continue to mash, stir, and simmer partially covered until the sauce reaches the consistency of a rich soup. (If you find you have too many or too large tomato seeds left in the sauce, you may run the sauce through a sieve, (strainer).
Set the sauce aside to cool or refrigerate before applying it to your pizza dough.)
